Your humble writer lived in North Texas for a number of years and is married to someone who went to college in Oklahoma.  In the decades just after the Civil War there was a sizable movement of African-Americans from the Deep South to the state of Texas and what was then the Oklahoma Territory.  All-Black towns thrived during this era.  Some of these locales became so successful that whites reacted violently to them in what were, in effect, pogroms.  This history was lost, often intentionally so, for decades and is only now being rediscovered.  Other times these towns declined for less dramatic reasons, such as changes in the economy.  These places, so far removed from many parts of the country, have fascinating stories that will hopefully be told before they are lost forever.  Here is a small clip from one of them.
